Trademarks only apply to the names of goods or service bing sold. So to get a trademark, there has to be a product like a Blue Ivy[tm] bib that is being sold. It would protect against another similar product being given that name or a confusingly similar name. Since people cannot be sold, another person could have the same name without confusion. The trademark cannot stop that.

Names do have economic value though. I think there was a study done that showed that those with "black" sounding names were less likely to get hired then "white" sounding names, even with the same application.
